COV Bystrice nad Olsi Wastewater Treatment Plant, Bystřice, Moravskoslezský kraj

COV Bystrice nad Olsi is a municipal wastewater treatment plant located in Bystřice, in the Moravskoslezský kraj region of the Czech Republic. The plant serves a population of approximately 10,213 people, placing it within the medium agglomeration category under EU classification. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies. The designed capacity is 4,000 m³/day, and the actual discharge volume is 907.07 m³/day, indicating operational headroom. The plant operates under Czech national regulations that implement the EU directive. The treated effluent is discharged into a local watercourse that ultimately drains into the Odra River basin, which flows northward to the Baltic Sea. The plant plays a key role in protecting the water quality of the region's rivers and supporting downstream aquatic ecosystems.

The plant discharges into a tributary of the Olše River, which joins the Odra River near the Czech-Polish border. The Odra River flows through Poland and Germany before reaching the Baltic Sea. The watershed supports diverse aquatic life and is an important ecological corridor in Central Europe. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water bodies from eutrophication.
